----------------------------+-----------------------------------------------
This patch fixes a minor memory leak in the chromatic polynomial code. It
appears to me that the mpz variables should be freed at the end of the
function.
I have also added additional tests.
The code appears not to be practical for graphs of order +15. I am
wondering if we could gain some speed by using memoization. It would
complicate the code quite a bit but it might be a drastic improvement!
